Parker Hannifin's Jet-Pipe Servo Valves
Presenter
James Hoke - Capital Projects Manager - Power Generation Jim started with Parker Hannifin in 1992 while earning his mechanical engineering degree from the University of Cincinnati. Jim has held many positions within Parker’s large organization, including: Engineering roles within Parker’s Tube Fittings Division (custom, short order, just in time fittings), a Chicago based sales position for Parker’s Instrumentation Group (compression fittings, valves, manifolds, regulators, etc), and as a Product Manager for Parker’s Partek Division (semiconductor grade liquid chemistry control) Jim currently supports the Power Generation sector with knowledge of Parker’s manufacturing capabilities, extensive OEM and Aftermarket products, and our regional engineering and Distribution resources..
Presentation Synopsis
- Parker’s “soft-fail” Abex servo valves will not cause the downstream actuator to fully extend or retract if plugged. The servo valve can also be spring-biased to move the actuator to a preferred safe position.
- The product is a drop-in replacement for many servo valves in use—including hydraulic mounting and electrical connections.
- Large orifice diameters allow contaminants to pass through instead of obstructing flow.
- Hydraulic spool, designed with a significant chip shear force, enables continued operation in hydraulic systems experiencing varnish buildup.
- The robust design allows extended intervals between PMs, calibrations, and tests.
Key Takeaways for Users
- Jet-Pipe design has been proven to successfully operate long term with contaminated hydraulic oil.
- Drop in replacement for many OEM supplied servos.
- Fails to neutral position in case of blockage.
- GE approved
